Restore precise wheel location and quiet, controlled handling with the Beck/Arnley Suspension Control Arm (MPN 102-7015), a rear left upper control arm that comes with the ball joint for a complete installation. It's an application-specific, direct-fit replacement for the 2007-2018 BMW X5 and 2008-2019 BMW X6 — see the Buyer's Guide tab for engine-level fitment.
A control arm connects the wheel hub/knuckle to the vehicle's structure, locating the wheel through suspension travel while its bushings and ball joint allow controlled movement. Worn bushings or a loose ball joint can show up as clunking, uneven tire wear, or wandering steering; if the original rear left upper arm is the cause, this unit replaces it.
- Complete assembly: Control arm supplied with the ball joint for a one-piece installation.
- Application-specific design: Built to match OE form, fit, and function for the listed foreign-nameplate applications.
- Durable construction: Steel, iron, or aluminum construction for durability and rust/corrosion resistance.
- Hardware where applicable: New hardware and bushings included where applicable.
Rear upper arms install as a left/right pair — for even, balanced handling, consider replacing the opposite side as well.
